Hi guys, I want to root my HTC desire A8181 v2.2.2 but I don't know how. I'm new with this rooting business and I would really appreciate it if someone can help me please. My HTC only have 136 mb internal memory which is really nothing. I can only download like 3 apps then my memory is low. Is there like a guide for dummies to show me how to root it? And what is the safest and easiest way to root my phone? And what files do I need to root it? And why do I have a red triangle with an exclamation mark on my phone if I go in to recovery mode? Help please?

Here is the details of my phone:
HTC desire A8181
V2.2.2
Baseband version - 32.49.00.32U_5.11.05.27
Kernel version - 2.6.32.15-gf5a401c
htc-kernel@and18-2#1
Build nr. 2.29.405.14 CL345208 release-keys
Software nr. 2.29.405.14
Browser version - WebKit 3.1

Please any help
Thanks
 
Specifically look at the guide to rooting using revolutionary, linked from the thread Bazcabs has provided a link to. Your software is too new to use the older (unrevoked) method, so you don't actually have a choice of method (do not use the official HTC bootloader unlock: that would prevent you from using some of the techniques which can increase your storage, will wipe your apps and data from your phone, and is no simpler to root with than using Revolutionary).

The red triangle/exclamation mark is the HTC recovery program. You have to use some combination of button presses to get the actual recovery menu, but you can't do what you want with the HTC recovery menu anyway. What the Revolutionary method does is:

* use Revolutionary to bypass your phone's security (makes the phone "S-Off")
* this allows you to replace your HTC recovery program with a custom one that allows you to install ("flash") custom software (rather than just HTC signed software).
* use the custom recovery to flash a file which will modify your ROM to give you root access (or to install a pre-rooted custom ROM).

The guide takes you through every step, but that's the principle. If you find yourself having trouble with the detail, remember that this is what it's all about - the rest is the details of how to actually do this or how to install the software on your computer and download the files you'll need.

The All Things Root Guide thread also contains links to a few other posts which might be useful. I'd particularly recommend reading the root memory faq if your main interest is getting more storage space, as that describes the 2 main methods which can be used.
 
Tnx guys for helping. Really appreciate it but im really struggling with the fastboot step.
Why does my computer say: 'fastboot' is not recognized as an internal or external command, oper
able program or batch file.
 
Congratulations :)

OK, let me say that I've not used my Desire for a year now, so I have no experience of KitKat ROMs for the Desire. I in fact used Gingerbread (2.3) ROMs for my daily use, as these worked better than any ICS ROMs, and were also faster than Jelly Bean on that hardware (though the JB ROM I played with was better than the ICS ROMs I'd tried). So I simply do not know how good the KK ROMs are, and cannot recommend which ones to try.

That said, the place to find ROMs is the Desire Android Development forum at XDA. There's an index thread there which will help you find your way round. The most important thing is to read the first couple of posts of each thread to find out what the requirements are for installing a particular ROM. In particular, what hboot and what size sdcard partition?

These are things described in the root memory faq in this forum. When loading a ROM that's smaller than the stock Sense ROM we would use custom hboots to reduce the size of the /system partition (where the ROM lives) and give more space for user apps. Many ROMs could use a second partition on the SD card to give you more space for installing apps. But if you want to install KK then these things are more important than giving more space. The KK ROM willprobably be larger than the stock HTC ROM, so you probably do not want to use a "smaller" hboot. That means you will need a partition to give you more app storage, but it's also likely that you'll need the partition to fit part of the ROM in (i.e. the ROM may well not install unless you have partitioned the card). This is why I say it's important to read the ROM's requirements before installing.

Partitioning the card will probably erase anything currently on it, so it's important to back your card up completely before starting to do that.

As for installing a ROM (assuming you've already partitioned the card), the procedure is:

* take a backup using your custom recovery (a "nandroid" backup). This will let you restore your old ROM and data if you need to. The nandroid backup is stored on your SD card.

* install Titanium Backup to back up your current apps/data if you wish to restore them on the new ROM (a nand backup restores the ROM as well, so can't be used for this purpose). Titanium Pro can back up messages in a format that be restored to a new ROM, but the free version does not, so if you use that you will need a second app to back up your message. If you do not sync your contacts with Google make sure you back them up too (you can just export them to the SD card from the phone app).

* To flash a ROM the general procedure is:
- download the ROM zip and copy it to your sd card
- go into recovery. Take a nandroid backup if you haven't done so recently.
- do a factory reset from recovery. You must not erase the SD card, but you do need to wipe the phone itself, as the system data will be incompatible with the new ROM
- select the "install zip" option from recovery. Select the ROM zip and install. Some ROMs include an installer script which may give you some choices to make.
- after installing the ROM, reboot the phone. The first boot may take a while, so don't panic.
- Once booted, set up the phone: enter your google login, re-sync your contacts, restore any user apps you want from Titanium (do not try to restore system apps or system settings - the point of the factory reset was to remove these data, so you'll just make trouble for yourself if you restore them again).
- If you don't like it or it doesn't work, restore your nandroid or try another ROM.

Note that a new ROM will be very different, so give it a bit of time to find out what it can do.

The various posts in the All Things Root Guide sticky post have more details about some of this stuff, but those are the principles. The main thing is to do the preparation, and with everything to read and make sure you know what you are doing before trying it.

Good luck :)
 
One question. So I rooted my phone...give me a summary of the whole upgrading to a better software thing.
Can I just download the Rom file and install it from recovery wha la done or is it more complicated, because this is really Greek to me in other words I don't understand it. Please tell me its simple.
Tnx and sorry if I'm really asking stupid questions.
 
Actually my last post was a description of how to do it. But to give an overview of that:

1) If the ROM needs any particular setup on your phone, such as an extra partition on the sd card, do that first.

2) Back up your current ROM and any important data. There are different types of backup for different purposes, so make sure you have all the backups you might possibly need. A recovery backup (nandroid) is the most important.

3) Copy the ROM zip onto the sd card.

4) Go into recovery. Factory reset. Install ROM from SD. Reboot.

5) Set up the phone again with your account and apps.

Step 1 is something you just do once (most KK ROMs will have the same requirement, most likely a 1 GB ext4 format partition on the card). The others can look like a lot at first, but become habit after a while.

The factory reset is necessary. If you try installing a ROM based on a different base from your current one without doing that there will be all sorts of strange bugs, if it even boots at all. So while it's a hassle there is no short cut. That's why you need to back up important user data and apps before changing ROM and then restore them afterwards.
 
Why does it say that I failed to install the ROM and I did wipe my phone and backed up my data? Am I doing something wrong? I'm installing 4.2.2 from AOKP
 
Can you tell us exactly what you did and what happened? All I know right now is that something says the install failed, which isn't enough to identify the problem.
 
http://forum.xda-developers.com/showthread.php?t=1863780

That's the link to the exact location and I downloaded the version 4.2.2 JB, the v2.2 gapp file. And when I did all the steps you told me it still says that I failed to install the ROM. It verifies and then it says something like "installation aborted" what am I doing wrong?
 
OK, it doesn't say that you need a partitioned SD card, but do you have one? Just for info.

You say "it verifies" and then says the installation aborts. So does it try to install, or does it just terminate after verification? If the latter, look in your recovery for an option to toggle or turn-off signature verification - if you have that turned on most things won't flash.
 
The xda thread you link to doesn't specify any requirements other than Stock hboot. I would contact the ROM developer & ask him if there are any other requirements.
 
Okay it seem to install after I disabled my verification but it still said error and failed to install. And when I wanted to switch my phone on again it went on but it is stuck on the white screen. It only shows HTC (in green) and it doesn't want to go further in other words it doesn't say "quietly brilliant" and boot on what's wrong with my phone now? Please any help. This is quiet hard.
 
OK, that ROM should fit without needing a partitioned card, though it's very tight (the /system folder is 246.5 MB, and the standard /system partition in a Desire is 250 MB - I downloaded it and had a look). Did you check the md5 code of the zip you downloaded? It's possible that you just have a bad download.

If the md5 is OK I can only suggest one of 2 things:

1) tell us exactly what you did and exactly what messages you got. To identify whether there was a problem with what you did we need more than "I followed the steps", because if you did something wrong that doesn't give us any way of spotting it.

2) try a different ROM.

If the install started and then failed you probably don't have a complete ROM, which is why it won't boot. To fix this, shut the phone down (pulling the battery out is fine), boot back into recovery and restore the backup you made before you tried to flash the ROM. Then your phone will be working again with the previous ROM and you've lost nothing but a bit of time.
 
If you took a backup before you tried flashing the ROM you can just restore that. Pull the battery out, leave in out for a minute (let the silicon discharge properly). Reinsert battery and boot while pressing the volume down key. That will take you to the bootloader, from where you can select recovery then restore the backup.

As long as your bootloader is intact (and a ROM flash cannot touch that) the phone is not truly bricked. A corrupted ROM can be fixed by restoring a recovery backup or flashing another ROM.
 
Why does my phone say insuficiant storage even tough I have over 50mb of internal storage and the app I want to download is only 20mb. Help please and thanks for all the help so far.

Btw I installed the v4.2.2 JB version...thanks a lot for the help guys.
 
The installed size of some apps can be rather larger than the download size (which is what the Play Store quotes I believe). You'll get the "insufficient storage" warning if the install will leave you with less than 10% of your internal storage remaining - if you've not changed that (e.g. using a custom hboot, which I don't think you have) that would be around 15MB.

You could try clearing caches and see whether that will let you install the app.
 
I do clear my caches but still it doesn't want to. Is there a way I can increase the storage or an app compressor or something I can download? Really appreciate the help.
